ANNOUNCEMENT IN RELATION TO THE MOVEMENT IN THE CLINPHONE SHARE PRICE

BOSTON, MA, February 15, 2008 - PAREXEL International Corporation ("PAREXEL") (Nasdaq: PRXL) notes the recent movement in the share price of ClinPhone plc ("ClinPhone" or the "Company"). Under the United Kingdom Takeover Code, PAREXEL confirms that it has made a preliminary proposal to the Board of ClinPhone in relation to a potential offer by PAREXEL for the entire issued and to be issued share capital of ClinPhone. While that preliminary proposal was rejected by the Board of ClinPhone, PAREXEL is currently evaluating its options in relation to ClinPhone. However, there can be no certainty that an offer for ClinPhone will be forthcoming.

Any offer, if made, is likely to be solely in cash. A further announcement will be made in due course.

Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the Code, if any person is, or becomes, "interested" (directly or indirectly) in 1% or more of any class of "relevant securities" of the Company, all "dealings" in any "relevant securities" of that company (including by means of an option in respect of, or a derivative referenced to, any such "relevant securities") must be publicly disclosed by no later than 3.30 pm (London time) on the London business day following the date of the relevant transaction. This requirement will continue until the date on which any offer becomes, or is declared, unconditional as to acceptances, lapses or is otherwise withdrawn or on which the "offer period" otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an "interest" in "relevant securities" of the Company, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the Code, all "dealings" in "relevant securities" of the Company by PAREXEL, or by any of its respective "associates", must be disclosed by no later than 12.00 noon (London time) on the London business day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose "relevant securities" "dealings" should be disclosed, and the number of such securities in issue, can be found on the Takeover Panel's website at www.thetakeoverpanel.org.uk.

"Interests in securities" arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an "interest" by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Code, which can also be found on the Panel's website. If you are in any doubt as to whether or not you are required to disclose a "dealing" under Rule 8, you should consult the Panel.
